Using an acid rest to lower ph

[darrenw]

Thanks,

Had a quick look at the water calculator here http://www.brewersfriend.com/mash-chemi ... alculator/, added my water profile,malt weight and color, adjusted the style and just need to add a little acid 3-4 ml, to adjust to 5.2. so bought some Phosphoric Acid (1l for £3.45) (should last me a while).
